[GitHub] [airflow] potiuk opened a new pull request, #26091: Improve the speed and stability of KPO tests

potiuk opened a new pull request, #26091:
URL: https://github.com/apache/airflow/pull/26091

   The KPO tests were occasionally failing in CI because of race
   condition between delete from previous test and running the
   following tests. Simply speaking the pods run via KPO well
   not immediately sometimes and the following test picked them
   together with the current pod and failed becasue of duplicate
   pods. There was even a tearDown Delay of 1 second introduced
   as workaround to combat this problem.
   
   This PR fixes it much better. Each POD in the KPO test gets
   unique label (derived from test name) and when executing the
   POD this label is then used as selector, so that only the
   **just started** POD in current test are selected - not any
   dangling pod (being deleted) from the previous tests.
   
   This not only removes flakiness of the tests, but also remove
   the need of sleep, which speeds up the whole suite by whoooping
   33 seconds (there were 33 tests to run).

   @ephraimbuddy  @dstandish  @jedcunningham  That was also the last blocker from #25678 which vastly improves the experience of running K8S tests and makes them exactly 1-1 to what CI will have. 
   
   I actually debugged and fixed the problem using the tools from #25678 and following the TESTING.rst guideline there on how to test (both got slightly improved as a result of this investigation and fix) - so I was eating our own dog food.
   
   I also know how to make it even better experience (By develoiping that I learned that new `Kind` apparently has ready-to use features for mounting sources to running containers so we will be able to  have a great development experience for K8S as well with realy quick iterations and feedback loop) without using Okteto or manually configuring Docker Desktop @jedcunningham  (our recent discussions) right after we merge #25678 as follow-up.. I am excited :)
